The Brother drum unit is a separate consumable that typically should be replaced after the use of 3 or 4 toner cartridges.  If you own any of the Brother laser printers listed below and you are getting a “Replace Drum” message on your machine’s display, it might be time to get a new drum.  Your printer uses a page counter to track usage, which must manually be reset every time a new drum unit is installed.  Instructions for both steps are included below!

Compatible Brother laser printers:

Brother HL‑L5000D / HL‑L5100DN / HL‑L5200DW / HL‑L5200DWT / HL‑L6200DW / HL‑L6200DWT

Replacing the DR-820 Drum Unit

  1. Turn on the printer and open the front cover.

  3. Release the toner cartridge from the drum assembly by pushing down on the green lock lever on the left side of the unit.
  4. Unbox the new drum unit.

  6. Install the complete unit back into the printer and close up the front cover.

Resetting the DR-820 Drum Counter

  1. Open the front cover of the machine.
  2. Press and hold “OK” to display the [Drum Unit] option and press “OK.”
